Essential fatty acids (EFAs) are "essential fats" and are required for optimal health. There are two main families of essential fats: omega-3 and omega-6. These fatty acids live in the cell membrane and compete. It is important to balance these fats for proper cell function. Consuming more omega-3s helps you balance any overabundance of omega-6 fats (from vegetable oils, processed food, and meat) for your cell health. Most experts agree we need a minimum of 500 mg EPA+DHA daily.
